I'd want the .yuv and corresponding .enc files after the cut (as I
said earlier, use imagemagik's 'display' to ensure you got the one you
want).  I expect that the .yuv file will look ok (none of those
blocks), but if not, that is a bad sign right there.

you get them  by using '-d 3' and you should send me 100 lines or so
before  the corresponding 'Converting ...' line (and probably 100lines
after too for good measure).  Also let me know if you are seeing those
QMAT_SHIFT messages.

If after all of that, I can't figure out what is going on, I could use
the 1st bit of your video, with a relevant cut point to duplicate the
issue.  Or if you prefer, you could do both, and save some back and
forth e-mail.
